Gotham
Gotham is a 1″ deflection spring hanger designed for acoustically isolated drywall ceilings. The Gotham spring features a 1.5″ thick neoprene element at the top and a channel clip assembly at the bottom for carrying a cold-rolled channel grid. Gotham springs are sold with project-specific shop drawings that detail the spring layout, spring deflections, seismic restraint, and installation sequencing. Acousthetics offers an optional service to have the shop drawings fully engineered and signed/stamped by a state-licensed third-party structural engineer.
What is the Gotham spring hanger?
The Gotham double-deflection spring-neoprene hanger is a high-performance acoustic ceiling hanger designed for concrete ceiling assemblies. It features a 1-inch static deflection spring combined with a neoprene isolator for superior sound and vibration isolation. The hanger includes a threaded bolt and a carrying clip for easy integration with a cold-rolled steel channel (CRC).
Does the Gotham spring hanger have a fire rating?
No, the Gotham spring hanger itself does not have a fire rating. However, it is designed for use in concrete assemblies, where the overall fire rating is determined by the concrete structure in which it is installed.
What are the most common applications for the Gotham spring hanger?
The Gotham spring hanger is engineered to provide exceptional airborne and impact sound isolation in concrete ceiling systems. Common applications include:
- Auditoriums and theaters
- Fitness centers and gyms
- Recording studios and dubbing stages
- Mechanical rooms
- Critical listening environments requiring low background noise
How is the Gotham spring hanger attached to the supporting slab?
The Gotham spring hanger can be securely installed using:
- Screw or wedge anchors
- Threaded rod hangers
How does the Gotham spring hanger compare to standard neoprene hangers?
The Gotham spring hanger provides significantly higher airborne and impact sound insulation than standard neoprene hangers. Its double-deflection spring design allows for greater vibration isolation, making it ideal for high-noise environments such as theaters, gyms, and mechanical rooms.
Can the Gotham spring hanger be used in seismic applications?
Yes, but for seismic restraint locations, a hanger with a threaded rod for uplift restraint is required. The Gotham hanger can be combined with seismic-rated hanger assemblies to comply with seismic building codes. This information will be included on shop drawings supplied by acousthetics.
What weight capacities does the Gotham spring hanger support?
The Gotham spring hanger is available in multiple spring ratings to accommodate a range of ceiling load requirements. Contact our team to determine the appropriate hanger for your specific weight and deflection needs.
Can the Gotham spring hanger be used with drywall ceilings?
Yes, the Gotham hanger is compatible with drywall ceilings when installed with a cold-rolled steel channel (CRC) grid. This ensures proper load distribution, even deflection of the springs, a flat ceiling, and top tier acoustic performance.
